Description

Output Input

GMAW-STT

Invertec®STT®II

Featuring the Surface Tension Transfer® (STT) Process

Control Heat Input, Spatter and Fume

The revolutionary STT II power source combines high frequency inverter technology with

advanced Waveform Control Technology™ to provide a better welding solution than

traditional short arc MIG. Unlike CV MIG machines, the STT machine has no voltage control

knob. STT uses current controls to adjust the heat independent of the wire feed speed, so

changes in electrode extension do not affect heat. Low heat input welds can be produced

without overheating or burning through, and distortion is minimized. Spatter and fumes are

reduced because the electrode is not overheated — even when welding with larger

diameter wires and 100% CO2shielding gas.

Waveform Control Technology®

Driving Superior Welding Performance

Lincoln’s Waveform Control Technology controls and shapes the output waveforms

(or weld modes) to adapt to virtually any application, material or weld position. Waveform

Control Technology makes it possible to take advantage of Lincoln Nextweld innovations like

the STT Process using the STT II.

For more information see Nextweld Document NX-1.10

WHAT IS NEXTWELD®?

Nextweld integrates Lincoln’s technologies, process-

es and products to create a comprehensive, flexible,

user-friendly welding system that can increase

efficiency and reduce fabrication costs. Waveform

Control Technology™ and digital communications

provide the foundation for Nextweld innovations like Pulse-On-

Pulse™, Power Mode™, STT®and ArcLink®. Look for Nextweld

for ultimate arc control, high efficiency/reliability and seamless

system integration.

STT®(Surface Tension Transfer®)is a controlled

GMAW short circuit transfer process that uses

current controls to adjust the heat independent of

wire feed speed, resulting in superior arc perform-

ance, good penetration, low heat input control,

and reduced spatter and fumes.

Document NX-2.20

circuit transfer using CO2

and .045” solid wire.

STT using CO2

and .045” solid wire.

Note reduced spatter and fume.

A. STT produces a uniform molten ball and maintains it

until the "ball' shorts to the puddle.

B. When the "ball" shorts to the puddle, the current is

reduced to a low level allowing the molten ball to wet

into the puddle.

C. Automatically, a precision PINCH CURRENT wave

form is applied to the short. During this time,

special circuitry determines that the short is about

to break and reduces the current to avoid the spatter

producing "explosion".

D. STT circuitry re-establishes the welding arc at a low

current level.

E. STT circuitry senses that the arc is re-established, and

automatically applies PEAK CURRENT, which sets the

proper arc length. Following PEAK CURRENT, internal

circuitry automatically switches to the BACKGROUND

CURRENT, which serves as a fine heat control.

A CLOSER LOOK

• Superior weld profile

(no wagon tracks)

• Slight convexity of root weld

• Low hydrogen deposit

Stick welding with cellulose

electrodes provides good fusion

characteristics, but leaves deep

wagon tracks (requiring more labor

for grinding), a very convex root

weld, and a high hydrogen

deposit.

Open Root Pass with STT

provides a weld ligament thickness

of approximately 0.22˝.

Electrode

USING STT FOR OPEN ROOT WELDING

Open root welding is used for pipe and single-sided plate welding in

situations that preclude welding from both sides of the material. This type

of welding is common in the petrochemical and process piping industries.

Advantages of STT Open Root

Penetration Control

• Provides reliable root pass and complete back bead. Ensures excellent

sidewall fusion.

Cost Reduction

• Uses 100% CO2, the lowest cost gas, when welding carbon steel.

Flexibility

• Provides the capability of welding stainless steel, nickel alloys, and mild

or high strength steels without compromising weld quality.

• Capable of welding out of position.

Low Heat Input

• Reduces burnthrough and distortion.

Low Hydrogen Weld Metal Deposit

Speed

• High quality open root welds at faster travel speeds than GTAW.

Current Control Independent of Wire Feed Speed

• Allows operator to control the heat input to the weld puddle.

Ease of Operator Use

• More forgiving process than conventional short arc welding with

CV machines.
